    <p>I have a serialized attribute in my model <code>serialize :vertices, Array</code>. All seems OK when using it, but after I reload the console (or on a web request) the serialized array is returned as a string, which is obviously not what I expected. Here is the same procedure in rails console:</p> <pre><code>ruby-1.9.2-p290 :009 &gt; g.vertices = [Vertex.new, Vertex.new] =&gt; [#&lt;Vertex:0x000000036315e8 @neighbours={}, @options={}, @name=nil, @real_name=nil, @teacher=nil, @discipline=nil, @student_group=nil&gt;, #&lt;Vertex:0x00000003631458 @neighbours={}, @options={}, @name=nil, @real_name=nil, @teacher=nil, @discipline=nil, @student_group=nil&gt;] ruby-1.9.2-p290 :010 &gt; g.inspect =&gt; "#&lt;Graph id: 17, vertices: [#&lt;Vertex:0x000000036315e8 @neighbours={}, @options={}, @name=nil, @real_name=nil, @teacher=nil, @discipline=nil, @student_group=nil&gt;, #&lt;Vertex:0x00000003631458 @neighbours={}, @options={}, @name=nil, @real_name=nil, @teacher=nil, @discipline=nil, @student_group=nil&gt;], oriented: true, max_index: 0, trigger_limit: nil, created_at: \"2011-11-01 09:13:40\", updated_at: \"2011-11-01 09:17:30\", name: nil&gt;" ruby-1.9.2-p290 :011 &gt; g.save (0.4ms) UPDATE "graphs" SET "vertices" = '--- - !ruby/object:Vertex neighbours: {} options: {} name: !!null real_name: !!null teacher: !!null discipline: !!null student_group: !!null - !ruby/object:Vertex neighbours: {} options: {} name: !!null real_name: !!null teacher: !!null discipline: !!null student_group: !!null ', "updated_at" = '2011-11-01 09:21:11.516199' WHERE "graphs"."id" = 17 =&gt; true ruby-1.9.2-p290 :012 &gt; g.inspect =&gt; "#&lt;Graph id: 17, vertices: [#&lt;Vertex:0x000000036315e8 @neighbours={}, @options={}, @name=nil, @real_name=nil, @teacher=nil, @discipline=nil, @student_group=nil&gt;, #&lt;Vertex:0x00000003631458 @neighbours={}, @options={}, @name=nil, @real_name=nil, @teacher=nil, @discipline=nil, @student_group=nil&gt;], oriented: true, max_index: 0, trigger_limit: nil, created_at: \"2011-11-01 09:13:40\", updated_at: \"2011-11-01 09:21:11\", name: nil&gt;" ruby-1.9.2-p290 :013 &gt; reload! Reloading... =&gt; true ruby-1.9.2-p290 :014 &gt; g = Graph.last Graph Load (0.1ms) SELECT "graphs".* FROM "graphs" ORDER BY "graphs"."id" DESC LIMIT 1 =&gt; #&lt;Graph id: 17, vertices: "---\n- !ruby/object:Vertex\n neighbours: {}\n option...", oriented: true, max_index: 0, trigger_limit: nil, created_at: "2011-11-01 09:13:40", updated_at: "2011-11-01 09:21:11", name: nil&gt; ruby-1.9.2-p290 :015 &gt; g.vertices.class =&gt; String ruby-1.9.2-p290 :016 &gt; </code></pre> <p>I guess its not deserializing properly (maybe because of my custom classes in the array?) Any tips would be really appreciated. Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
